What have you got maintenance_work_mem set to?

maintenance_work_mem = 1GB

So evidently, when it tries to actually allocate 1GB, it can't do it.
Ergo, that setting is too high for your machine.

AHhh, ok. I was thinking that it was filling up the 1GB i allocated to it.

I just dropped the memory allocated to the instance down by about 10GB and i'm still getting the error though.

seems like i've got 2GB free.

Food for thought..

I'll look more into it tomorrow morning though.

Thanks

Dave
